Controlled in situ growth of tunable plasmonic self-assembled nanoparticle arrays
SHVETS, IGOR; MCGILP, JOHN; FLEISCHER, KARSTEN; FOX, DANIEL (2012)Self-assembled silver nanoparticle (NP) arrays were produced by deposition at glancing angles on transparent stepped Al2O3 templates. The evolution of the plasmonic resonances has been monitored using reflection anisotropy ... -
General approach to the analysis of plasmonic structures using spectroscopic ellipsometry
FOX, DANIEL; FLEISCHER, KARSTEN; SMITH, CHRISTOPHER; ZHANG, HONGZHOU; MCGILP, JOHN; SHVETS, IGOR (2013)In this article a route to analyze the full optical response of plasmonic structures is developed. First, the simple case of an anisotropic thin plasmonic layer supported on a transparent substrate is analyzed by ... -
Group V adsorbate structure on vicinal Ge(001) surfaces determined from the optical spectrum
PATTERSON, CHARLES; MCGILP, JOHN (2017) -
In situ characterization of one-dimensional plasmonic Ag nanocluster arrays
SHVETS, IGOR; FLEISCHER, KARSTEN; MCGILP, JOHN (2011)One-dimensional Ag nanoparticle arrays have been grown on step-bunched vicinal Al2O3 in ultrahigh vacuum using deposition at a glancing angle. The structures grown showed a strong optical anisotropy in the visible region ... -
In-situ characterisation of one-dimensional plasmonic Ag nanocluster arrays
SHVETS, IGOR; MCGILP, JOHN; FLEISCHER, KARSTEN (2011)One-dimensional Ag nanoparticle arrays have been grown on step-bunched vicinal Al2O3 in ultrahigh vacuum using deposition at a glancing angle. The structures grown showed a strong optical anisotropy in the visible region ... -
Manipulating and probing the growth of plasmonic nanoparticle arrays using light
BULFIN, BRENDAN; FLEISCHER, KARSTEN; USOV, VICTOR; MCGILP, JOHN; SHVETS, IGOR (2013)Highly ordered self-assembled silver nanoparticle (NP) arrays have been produced by glancing angle deposition on faceted c-plane Al2O3 templates. The NP shape can be tuned by changing the substrate temperature during ... -
Optical and phonon excitations of modified Pandey chains at the Si(111)-2×1 surface
PATTERSON, CHARLES; MCGILP, JOHN (2011)The modified Pandey π-bonded chain structure for the (2×1) reconstruction of the Si(111) surface has two nearly degenerate structures in which one or the other of two atoms in the π chain is the outermost atom at the ... -
Optical characterisation of plasmonic nanostructures on planar substrates using second harmonic generation
MCGILP, JOHN; FLEISCHER, KARSTEN; SHVETS, IGOR (2015) -
Optical Fingerprints of Si Honeycomb Chains and Atomic Gold Wires on the Si(111)-(5x2)-Au Surface
MCGILP, JOHN (2013)The intensively studied Si(111)-(5×2)-Au surface is reexamined using reflectance anisotropy spectroscopy and density functional theory simulations. We identify distinctive spectral features relating directly to local ... -
Probing the out-of-plane optical response of plasmonic nanostructures using spectroscopic ellipsometry
SHVETS, IGOR; MCGILP, JOHN; FLEISCHER, KARSTEN; SMITH, CHRISTOPHER (2011)A simplified approach to investigate the out-of-plane response of plasmonic nanostructures using spectroscopic ellipsometry (SE) is presented. One-dimensional self-assembled arrays of Ag nanoparticles (NP?s) were grown on ... -
Reflectance anisotropy spectroscopy of magnetite (110) surfaces
MAUIT, OZHET; SMITH, CHRISTOPHER; FLEISCHER, KARSTEN; FARRELL, LEO; MCGILP, JOHN; SHVETS, IGOR (2014)Reflectance anisotropy spectroscopy (RAS) has been used to measure the optical anisotropies of bulk and thin-film Fe3O4(110) surfaces. The spectra indicate that small shifts in energy of the optical transitions, ...
